pub struct Cursor<'a, K>where
K: 'a,{ /* private fields */ }btree_cursors)mtls only.Expand description
A cursor over a BTreeSet.
A Cursor is like an iterator, except that it can freely seek back-and-forth.
Cursors always point to a gap between two elements in the set, and can operate on the two immediately adjacent elements.
A Cursor is created with the BTreeSet::lower_bound and BTreeSet::upper_bound methods.
Implementations§
source§impl<'a, K> Cursor<'a, K>
impl<'a, K> Cursor<'a, K>
sourcepub fn next(&mut self) -> Option<&'a K>
🔬This is a nightly-only experimental API. (btree_cursors)
pub fn next(&mut self) -> Option<&'a K>
btree_cursors)Advances the cursor to the next gap, returning the element that it moved over.
If the cursor is already at the end of the set then None is returned
and the cursor is not moved.
sourcepub fn prev(&mut self) -> Option<&'a K>
🔬This is a nightly-only experimental API. (btree_cursors)
pub fn prev(&mut self) -> Option<&'a K>
btree_cursors)Advances the cursor to the previous gap, returning the element that it moved over.
If the cursor is already at the start of the set then None is returned
and the cursor is not moved.

source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();source§fn bright_black(&self) -> Painted<&T>

Returns a styled value derived from self with the background set to

builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():

fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};

fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
